Closing complaint without fixing issue

After posting on Hello Peter, I got a generic message. Then about 8 days later I get the following message

"Good day, Thank you for affording us the opportunity to review the complaint. Kindly note we have been advised by our servicing department that feedback was provided and the matter has been resolved. they even advised that you where only charged 10 for the debit order that returned. I trust you find the above well and will be closing the complaint."

They have not however sorted out the issue at hand! Spending nearly R100 on airtime to sort out an issue that was only created because of their incompetence! This issue I definitely NOT resolved!! I demand my airtime to be reimbursed!!
